dtslint changes output type based on $ExpectType values

Hi,
I'm looking at commit 886607f and trying to get the tests to pass by modifying Line 379.

Currently I get the error:

ERROR: 380:1  expect  TypeScript@4.9 expected type to be:
  Page | Post
got:
  Page<"edit"> | Post<"edit">

however, if I change the expected value to be the returned value, I get

ERROR: 380:1  expect  TypeScript@4.9 expected type to be:
  Page<"edit"> | Post<"edit">
got:
  Page | Post

so it seems like dtslint can't decide whether it wants the type parameter ("edit" is actually the default value) or not.

I managed to track the issue down to

DefinitelyTyped-tools/packages/dtslint/src/rules/expectRule.ts

Lines 414 to 420 in 15d48f4

    
           const actual = type 
        
             ? checker.typeToString(type, /*enclosingDeclaration*/ undefined, ts.TypeFormatFlags.NoTruncation) 
        
             : ""; 
        
           if (!expected.split(/\s*\|\|\s*/).some((s) => actual === s || matchReadonlyArray(actual, s))) { 
        
             unmetExpectations.push({ node, expected, actual }); 
        
           }

So... it seems TypeScript itself is changing the type output based on the surroundings?

Possibly related:

Ok, I'm dumb, the 2 errors were on different TS versions.

	const actual = type
	? checker.typeToString(type, /enclosingDeclaration/ undefined, ts.TypeFormatFlags.NoTruncation)
	: "";

	if (!expected.split(/\s\\|\\|\s/).some((s) => actual === s \|\| matchReadonlyArray(actual, s))) {
	unmetExpectations.push({ node, expected, actual });
	}
